For ensuring uniform braking from both wheels both brake disks should have a surface with an identical roughness. Therefore it is necessary to replace or pierce surely both disks at the same time. In repair trucks the brake disk can be checked on palpation. The most admissible palpation makes 0.2 mm (the established disk means).

5. Adjust the parking brake, address to the Section Adjustment of the parking brake. 6. Establish and fix back wheels. Do not oil fastening bolts. Wheels establish so that the markings put at removal coincided. Lower the car on wheels, tighten fastening bolts cross-wise the moment of 100 Nanometers.

Several times strongly press a brake pedal so that resistance was felt. Thus brake shoes will nestle on a disk and will occupy the working situation.

7. Check level of brake liquid in the tank. If necessary add it to MAX mark. Attention, check reliability: a) Whether brake hoses are fixed? b) Whether the brake hose in the holder is fixed? c) Whether the union of removal of air is tightened? d) Whether enough brake liquid in the tank? e) On the working engine check tightness of system. For this purpose press a brake pedal effort of 200-300 N (20-30 kg) and hold it during 10 pages. The effort of pressure of a pedal of a brake to a foot should not weaken. f) Check all connections on tightness.

New brake disks should be earned carefully extra in three stages. Stage 1: 5 strong braking since speed of 50 km/h on the road without transport. Stage 2: let's to a brake be cooled. Stage 3: 5 braking for speed of 50 km/h.
